B3 (B-cubed) stays for Biodiversity Building Blocks for policy and it is an upcoming Horizon Europe project that will use the concept of data cubes to simplify and standardize access to biodiversity data using the Essential Biodiversity Variables framework. These cubes will be used, in conjunction with other environmental data and scenarios, as the basis for models and indicators of past, current and future biodiversity. The overarching goal of the project is to provide easy access to tools in a cloud computing environment, in real-time and on-demand, with state-of-the-art prediction models of biodiversity, that will output models and indicators of biodiversity status and change. At the workshop organized by the Open-Earth-Monitor project in Athens during the EuroGEO 2022, Quentin Groom from the Plantentuin Meise presented the B3 project.
